Description

The present invention relates to a door hole cap mounting structure, a door hole cap, and a sealing member.

Conventionally, door hole caps have been used to prevent rainwater and the like from entering the inside of a vehicle through a door hole formed in a door inner panel of a vehicle door. The door hole cap needs to be removed from the door hole when carrying out work such as repair, and it is preferable that the door hole cap has a structure that can be attached and detached multiple times.

For example, Patent Document 1 discloses a hole plug capable of closing a large number of holes provided in a plate material constituting an underbody of an automobile. This hole is used as a discharge hole to discharge excess paint during car body painting work, and after painting is completed, a portion of the hole is used as a mounting hole for attaching various accessories or as an insertion hole for inserting a wire harness. It is something that will be done. For holes that are not used as mounting holes or insertion holes, in order to prevent water and dust from entering the vehicle body through the hole, a hole plug that can close the hole is attached to the plate material. It has become.

The hole plug disclosed in Patent Document 1 has a first seal portion and a second seal portion that abut the peripheral edge of the hole at the tip of the peripheral wall portion, and the peripheral wall is disposed between the first seal portion and the second seal portion. A deformable part surrounded by a deformable part that can be displaced inward is formed. Since the hole plug is formed with a deformable portion, the insertion force required when inserting the hole plug into the hole is small, making it easier to attach the hole plug to the hole.

However, when the hole plug mounting structure disclosed in Patent Document 1 is applied to the door hole cap mounting structure, there is a problem that it is difficult to suitably fit the door hole in the door inner panel. The reasons why it is difficult to apply the hole plug mounting structure to the door hole cap mounting structure will be explained below.

First, the thickness of the plate material is about one-fourth of the width (cross-sectional width) of the hole plug in the direction from the outside to the inside of the car, but the thickness of the door inner panel is about 1/4 of the cross-sectional width of the door hole cap. The thickness is about 1/20th. As described above, the cross-sectional width of the door inner panel relative to the cross-sectional width of the door hole cap is extremely small compared to the cross-sectional width of the plate material relative to the cross-sectional width of the hole plug. Therefore, when the hole plug mounting structure is applied to the door hole cap mounting structure, the pressure of the first seal part and the second seal part against the door hole periphery decreases, and the door hole cap is attached to the door inner panel. The adhesion to the product decreases.

In addition, the cross section of the opening edge of the hole to which the hole plug is attached has a flat shape, whereas the cross section of the peripheral edge of the door hole to which the door hole cap is attached has a curved edge toward the outside of the vehicle. , has a bent end. There are manufacturing variations in the shape of this tip bent portion, and it is difficult for the hole plug mounting structure to change the shape of the hole plug to follow this manufacturing variation. Furthermore, when the shape of the opening edge of the hole as seen from the side of the vehicle changes significantly, it is difficult to change the shape of the hole plug to follow the shape. Therefore, when the mounting structure for a hole plug is applied to the mounting structure for a door hole cap, the door hole cap cannot follow the shape of the peripheral edge of the door hole, resulting in a decrease in water-stopping properties.

Furthermore, hole plugs are integrally molded by injection molding, etc., and it is not possible to make the cross-sectional shape of the hole plug a complicated shape including a hollow part, or to construct the hole plug from multiple materials with different hardnesses. It was difficult. Further, according to the description in Patent Document 1, the synthetic resin material forming the hole plug has a Shore A hardness of A60 to A95. Therefore, when the hole plug mounting structure is applied to the door hole cap mounting structure, the material hardness of the door hole cap is too high, so the pressure of the first seal part and the second seal part against the door hole periphery is reduced. will decrease. Therefore, it is thought that the adhesion of the door hole cap to the door inner panel decreases.

One aspect of the present invention has been made in view of the above-mentioned problems, and its purpose is to improve the pressure bonding force and adhesion force to the door inner panel, maintain good water-tightness, and provide a door with a wide variety of shapes. It is an object of the present invention to provide a mounting structure for a door hole cap that is suitable for a door hole.

In order to solve the above problems, a door hole cap mounting structure according to one aspect of the present invention is a door hole cap mounting structure that is attached to a first peripheral edge of a door hole formed in an automobile door inner panel. The door hole cap includes a plate-shaped cap member, a seal member attached to a second peripheral edge of the cap member, and the seal member includes a mounting base attached to the second peripheral edge. , an outer wall extending from the outer side end of the mounting base toward the first peripheral edge side, a connecting portion extending from the inner side of the outer wall toward the inner side of the vehicle, and an inner side end of the connecting portion. a seal lip extending toward the vehicle-inside surface of the door inner panel; and a bridge connecting surfaces of the connecting portion and the seal lip that are opposed to each other, and the tip portion of the outer wall is The seal lip contacts the door inner panel from the outside of the vehicle, and the tip of the seal lip contacts the inner surface of the door inner panel.

According to the above configuration, the tip portion of the outer wall contacts the door inner panel from the outside of the vehicle, and the tip of the seal lip comes into contact with the surface of the door inner panel on the inside of the vehicle. In other words, the sealing member supports the door hole cap from both the outside and inside of the vehicle, and is configured to maintain the position of the sealing member at the first peripheral edge. In addition, when a reaction force is applied to the tip of the seal lip and the tip of the outer wall, the seal member is stabilized at the designed position of the first peripheral edge because the seal member is provided with a bridge. The seal lip can be held and the reaction force applied to the tip of the seal lip can be stably ensured. Therefore, even if rainwater or the like tries to enter from outside the vehicle, the sealing member is stably pressed against the first peripheral edge, so that the door hole cap maintains good water-stopping properties.

Further, according to the above configuration, the mounting base, the outer wall, and the connecting portion form a deformable portion between the mounting base and the connecting portion. Thereby, when the sealing member is attached to the first peripheral edge, the sealing member can be deformed to follow the shape of the bent or curved corner of the first peripheral edge when viewed from the side of the vehicle. Therefore, even if there are manufacturing variations in the shape of the door hole when viewed from the side of the vehicle, the door hole cap can fit these door holes well.

In the door hole cap mounting structure according to one aspect of the present invention, the sealing member has a locking portion in which a foam is disposed at a tip portion of the outer wall, and the foam is attached to the first peripheral edge. It may also be pressed.

According to the configuration, the foam is pressed against the first peripheral edge, and the foam can be elastically deformed to match the shape of the first peripheral edge. Therefore, when the sealing member is attached to the first peripheral edge, the adhesive force of the sealing member to the first peripheral edge increases due to the elastic force of the foam. Therefore, even if rainwater or the like tries to enter from outside the vehicle, the door hole cap maintains good water-stopping properties.

Furthermore, since the foam elastically deforms to match the bent shape of the tip of the first peripheral edge, when the sealing member is attached to the first peripheral edge, the foam conforms to the bent shape of the tip of the first peripheral edge. Become. Therefore, even if there are manufacturing variations in the bent shape of the tip of the first peripheral portion, the door hole cap can fit these door holes well.

The door hole cap mounting structure according to one aspect of the present invention extends from the vehicle inner side end of the mounting base toward the first peripheral edge side, and connects to the connecting portion from the second peripheral edge side. It may have an inner wall.

According to the above configuration, when the seal member is attached to the first peripheral portion, when a reaction force acts on each of the seal lip and the tip of the outer wall, the seal member has an inner wall, so that the shape of the seal member is improved. can be kept stable. In other words, by attaching the door hole cap to the corner portion where the radius of curvature of the first peripheral portion is larger than when the seal member does not have an inner wall, even if the shape of the seal member is deformed, the shape of the seal member remains unchanged. can be maintained stably within the designed range. Therefore, even if there are manufacturing variations in the shape of the corner portions of the first peripheral portion, the door hole cap can fit these door holes well.

In the door hole cap mounting structure according to one aspect of the present invention, an end surface of the inner wall connected to the connecting portion and an end surface of the bridge connecting to the connecting portion may be opposed to each other via the connecting portion. good.

According to the configuration, the inner wall and the end surfaces of the bridge that connect to the connecting portion face each other via the connecting portion. Therefore, when the sealing member is attached to the first peripheral edge, the force applied from the second peripheral edge side and the force applied from the first peripheral edge side to the part of the connecting part where the inner wall and the bridge face each other are opposite to each other. to work. Thereby, the shape of the sealing member can be maintained more stably. Therefore, by attaching the door hole cap to the corner portion of the first peripheral portion with a small radius of curvature, even if the shape of the seal member is deformed, the shape of the seal member can be kept more stably within the designed range. can. Therefore, even if there are manufacturing variations in the shape of door holes, the door hole cap can fit these door holes well.

In the door hole cap mounting structure according to one aspect of the present invention, the cap member has a wide portion in which the second peripheral edge portion is wider in a direction from the outside of the vehicle to the inside of the vehicle than the inside portion of the cap member. It may have.

According to the above configuration, since the second peripheral portion of the cap member has the wide portion, the seal member can be firmly fixed to the cap member. Therefore, the stability of attaching the door hole cap is improved.

In the door hole cap mounting structure according to one aspect of the present invention, a mounting recess is formed in the second peripheral portion, and a mounting recess is formed on the second peripheral portion side of the mounting base to fit into the mounting recess. A mounting convex portion may be formed.

According to the above configuration, the mounting is performed by fitting the mounting convex portion of the mounting base and the mounting recessed portion of the second peripheral portion. With such a configuration, the sealing member can be more firmly fixed to the cap member, and the stability of attaching the door hole cap is improved.

In the door hole cap mounting structure according to one aspect of the present invention, the sealing member may be manufactured by extrusion molding.

The seal member is formed from a plurality of different materials, such as non-foamed and foamed materials. Therefore, according to the configuration, by manufacturing the seal member by extrusion molding, manufacturing becomes easier compared to other manufacturing methods such as molding using different materials.

The door hole cap 1 closes the door hole D2 by attaching the sealing member 20 attached to the cap member 10 to the first peripheral edge D3 of the door hole D2.

Note that the above-described attachment of the door hole cap 1 is merely an example. For example, the automobile door to which the door hole cap 1 is attached is not limited to the front door D shown in the example of FIG. 1, but may be any type of automobile door. Therefore, the door hole cap 1 may be attached to, for example, a rear door or a sliding door (not shown). Furthermore, the door hole cap 1 can be attached to any type of automobile, including sedan cars, hardtop cars, and convertible cars.

<Structure of door hole cap 1>
The structure of the door hole cap 1 will be explained with reference to FIG. 2. Note that FIG. 2 is a cross-sectional view taken along the line AA of the door hole cap 1 attached to the first peripheral portion D3 shown in FIG. Therefore, in the example of Figure 2, the top side of the paper is the top of the vehicle, the bottom is the bottom of the vehicle, the right side is the outside of the car (outside the car), the left side is the inside of the car (inside the car), and the near side of the page is the front side (front side). , the back side of the page corresponds to the rear side.

As shown in FIG. 2, the door hole cap 1 has a structure in which a sealing member 20 is attached to the second peripheral edge 11 of a plate-shaped cap member 10. The door hole cap 1 is attached to the first peripheral edge portion D3 by the sealing member 20 sandwiching the door inner panel D1 from both the outside and inside of the vehicle.

The cap member 10 is a plate-like member that has a similar shape to the door hole D2 in a side view of the vehicle and is slightly smaller than the door hole D2. As shown in FIG. 2, the sealing member 20 is attached to the second peripheral portion 11, so that the cap member 10 has a structure in which the entire circumference is surrounded by the sealing member 20.

Examples of the material for the cap member 10 include vulcanized rubber, thermoplastic elastomer, and thermoplastic resin.

<Structure of seal member 20>
The structure of the seal member 20 will be described with reference to FIG. 3. Note that FIG. 3 is an enlarged cross-sectional view of the vicinity of the seal member 20 in FIG. 2.

The seal member 20 supports the cap member 10 that closes the door hole D2 by having one end attached to the first peripheral edge D3 and the other end attached to the second peripheral edge 11. As shown in FIG. 3, the seal member 20 in this embodiment includes a mounting base 21, an outer wall 22, a connecting portion 23, a seal lip 24, a bridge 25, an inner wall 26, and a locking portion 41.

The attachment base 21 fixes the seal member 20 to the cap member 10 by being attached to the second peripheral portion 11 . An outer wall 22 extends from the outer side end of the mounting base 21 toward the first peripheral edge D3, and a connecting portion 23 extends toward the inner side of the vehicle from the inner side of the outer wall 22. A seal lip 24 extends from the inner side end of the connecting portion 23 toward the inner side surface of the door inner panel D1. connected by.

In this embodiment, as shown in FIG. 3, the sealing member 20 has a locking portion 41 in which a foam 30 is disposed at the tip of the outer wall 22. As shown in FIG. More specifically, the foam 30 is disposed between the tip 27 of the outer wall 22 and the connecting portion 23. The foam 30 in the locking portion 41 is pressed against the first peripheral portion D3. However, the present invention is not limited thereto, and the seal member 20 may be attached so as to sandwich the first circumferential edge portion D3 from both sides of the outside and inside of the vehicle.

That is, the foam 30 of the locking portion 41 is in elastic contact with the door inner panel D1 from the outside of the vehicle, and the tip 28 of the seal lip 24 is in contact with the surface of the door inner panel D1 on the inside of the vehicle. Therefore, the door hole cap 1 maintains the position of the seal member 20 on the first peripheral edge portion D3 by supporting the seal member 20 from both the outside and inside of the vehicle. Note that the seal member 20 does not need to include the locking portion 41. In this case, the tip 27 of the outer wall 22 may be in direct contact with the door inner panel D1 from the outside of the vehicle so as to sandwich the first peripheral edge D3. That is, the tip portion of the outer wall 22 may be the tip 27 of the outer wall 22 or the foam 30 of the locking portion 41. The tip portion of the outer wall 22 refers to the portion that comes into contact with the door inner panel D1 from the outside of the vehicle.

When the seal member 20 is attached to the first peripheral edge D3, a reaction force acts on the tip end portion of the outer wall 22 and the tip end 28 of the seal lip 24, so that the seal member 20 maintains the attached posture. . In particular, since the sealing member 20 includes the bridge 25, the shape of the sealing member 20 does not easily bend even if a reaction force is applied to the tip 28 of the sealing lip 24. Thereby, the reaction force applied to the tip 28 of the seal lip 24 can be stably ensured. Therefore, when a reaction force is applied to the distal end portion of the outer wall 22 and the distal end 28 of the seal lip 24, the position of the seal member 20 can be stably maintained at the designed position of the first peripheral edge portion D3. Therefore, even if rainwater or the like tries to enter from outside the vehicle, the sealing member 20 is stably pressed against the first peripheral portion D3, so that the water-stopping property of the door hole cap 1 is maintained satisfactorily.

Note that when the sealing member 20 has the locking portion 41, the foam 30 is pressed against the first peripheral edge D3, so that the foam 30 is aligned with the bent shape of the tip of the first peripheral edge D3. It can be elastically deformed. Therefore, when the sealing member 20 is attached to the first peripheral edge D3, the adhesive force of the sealing member 20 to the first peripheral edge D3 increases due to the elastic force of the foam 30 with respect to the first peripheral edge D3. Therefore, even if rainwater or the like tries to enter from outside the vehicle, the sealing member 20 is stably in close contact with the first peripheral edge D3, so that the water-stopping property of the door hole cap 1 is maintained satisfactorily.

Furthermore, since the foam 30 elastically deforms to match the shape of the first peripheral edge D3, when the sealing member 20 is attached to the first peripheral edge D3, the foam 30 conforms to the bent shape of the tip of the first peripheral edge D3. It can be followed and transformed. Therefore, even if there are manufacturing variations in the bent shape of the tip of the first peripheral edge portion D3, the door hole cap 1 can suitably fit these door holes D2.

Further, in this embodiment, as shown in FIG. 3, the seal member 20 has an inner wall 26. The inner wall 26 extends from the vehicle-inside end of the mounting base 21 toward the first peripheral edge D3 side, and connects to the connecting portion 23 from the second peripheral edge 11 side. Therefore, in this embodiment, the hollow part 42 is formed by the mounting base 21, the outer wall 22, the connecting part 23, and the inner wall 26. That is, the seal member 20 has a deformable portion formed between the mounting base 21 and the connecting portion 23. Further, in the sealing member 20 in which the hollow portion 42 is formed, the deformable portion has a shape that is slightly less flexible than in the case where the inner wall 26 is not provided. However, the present invention is not limited to this, and a space is formed at the same position as the hollow part 42 by the mounting base 21, the outer wall 22, and the connecting part 23, and a space is formed between the mounting base 21 and the connecting part 23. It suffices if it is formed to be deformable.

When the seal member 20 is attached to the first peripheral edge D3, the deformable portion can be deformed to follow the bent or curved shape of the first peripheral edge D3 when viewed from the side of the vehicle. Therefore, even if there are manufacturing variations in the shape of the door holes D2 when viewed from the side of the vehicle, the door hole cap 1 can fit these door holes D2 well.

Note that when the seal member 20 has the inner wall 26, when the seal member 20 is attached to the first peripheral edge D3 and a reaction force acts on each of the tip 27 of the outer wall 22 and the tip 28 of the seal lip 24, The shape of the hollow portion 42 can be maintained more stably. In other words, even if the shape of the seal member 20 is deformed by being attached to the corner portion R1 where the radius of curvature of the first peripheral portion D3 is larger than that in the case where the hollow portion 42 is not formed, the shape of the seal member 20 is designed. can be maintained stably within the specified range. Therefore, even if there are manufacturing variations in the shape of the door holes D2 when viewed from the side of the vehicle, the door hole cap 1 can fit these door holes D2 well.

In addition, in this embodiment, as shown in FIG. Although they are opposed to each other, the present invention is not limited thereto. Note that when the end surfaces of the inner wall 26 and the bridge 25 that connect to the connecting portion 23 are facing each other via the connecting portion 23, in the connecting portion 23 where the end surfaces are facing each other, from the second peripheral edge portion 11 side This force and the force applied from the first peripheral edge portion D3 side act oppositely. Therefore, when the seal member 20 is attached to the first peripheral portion D3, the seal member 20 becomes more difficult to deform, and the shape of the seal member 20 can be maintained more stably. In other words, the sealing member 20 is attached to the corner R2 of the first peripheral edge D3 having a small radius of curvature, and even if the shape of the sealing member 20 is deformed, the shape of the sealing member 20 can be kept more stable within the designed range. can be kept. Therefore, even if there are manufacturing variations in the shape of the door holes D2 when viewed from the side of the vehicle, the door hole cap 1 can fit these door holes D2 well.

Each part of the sealing member 20 other than the foam 30 may be mainly made of vulcanized rubber, thermoplastic elastomer, thermoplastic resin, or the like. As the material for the vulcanized rubber, for example, EPDM, IR, CR, styrene-butadiene rubber, or acrylonitrile-butadiene rubber can be used. As the material for the thermoplastic elastomer, for example, olefin type or styrene type can be used. As the thermoplastic resin material, for example, PE, PP, EVA, or soft polyvinyl chloride can be used. It is preferable that the material of the seal member 20 is formed into a solid shape.

It is preferable that the foam 30 is mainly made of synthetic rubber such as EPDM. Further, the foam 30 may be formed of the same material as the seal member 20, but in that case, it is formed not in a solid shape but in a foamed sponge shape. For example, it is particularly preferable that the foam 30 is made of a highly foamed EPDM material. The specific gravity of the highly foamed material is preferably about 0.05 to 0.30, for example.

Moreover, it is preferable that the sealing member 20 is manufactured by extrusion molding. By manufacturing the sealing member 20 by extrusion molding, it is possible to simultaneously manufacture different materials integrally, such as integrally molding a foam part such as the foam 30 and other non-foam parts at the same time. , manufacturing is easier than other manufacturing methods such as molding. This is because the sealing member 20 formed from a plurality of materials can be manufactured by one extrusion molding.

<Example of fixation and integration of cap member 10 and seal member 20>
In this embodiment, as shown in FIG. 3, the cap member 10 has a wide portion 12 at the second peripheral portion 11. As shown in FIG. The wide portion 12 is a portion that is wider in width than the inner portion 13 of the cap member 10 in the direction from the outside to the inside of the vehicle. However, the present invention is not limited to this, and the cap member 10 may have a structure in which the seal member 20 is attached to the second peripheral portion 11. In addition, when the second peripheral edge part 11 has the wide part 12, the area of the contact surface between the cap member 10 and the seal member 20 increases by increasing the width of the second peripheral edge part 11. Therefore, the seal member 20 can be firmly fixed to the cap member 10. Therefore, the stability of attaching the door hole cap 1 is improved.

Moreover, as for the specific method of fixing and integrating the cap member 10 and the seal member 20, the following methods may be mentioned, but the method is not limited thereto. (1) In advance, only the sealing member 20 is created by extrusion molding, and the sealing member 20 is set in a cavity (space) of a mold (not shown). Then, by injecting and injecting a molding material for the cap member 10 into the cavity, the cap member 10 is molded and at the same time, the cap member 10 and the seal member 20 are joined or integrated. (2) The cap member 10 and the seal member 20 are each created in advance, and the "thermal bonding" and "pressing with a mold (not shown)" described in JP-A No. 2002-096695 are performed. They may be fixed or integrated using a "hot melt adhesive" or "double-sided tape," or mechanically fixed or integrated using a "clip (not shown)."

Moreover, in this embodiment, as shown in FIG. A mounting convex portion 29 is formed. The seal member 20 is fixed to the cap member 10 by fitting the mounting convex portion 29 of the mounting base 21 into the mounting recess 14 of the second peripheral portion 11 . Therefore, the seal member 20 can be more firmly fixed to the cap member 10, and the stability of attachment of the door hole cap 1 is improved.

However, the present invention is not limited to this, as long as the second peripheral portion 11 and the attachment base 21 are fixed. For example, two mounting recesses and two mounting projections may be formed to more firmly fix the seal member 20 to the cap member 10 (not shown). Alternatively, the sealing member 20 may be fixed to the cap member 10 by forming triangular irregularities on the second peripheral edge portion 11 and the second peripheral edge portion 11 side of the mounting base 21 and fitting them into each other. Good (not shown).

<Variations of seal members>

Reference numerals 401 and 402 in FIG. 4 are cross-sectional views of seal members 201 and 202 according to another embodiment of the seal member according to the present invention.

First, the sealing member according to an embodiment of the present invention may be a sealing member 201 in which the inner wall 26 connecting the mounting base 21 and the connecting portion 23 is not formed, as shown by the reference numeral 401 in FIG. . In other words, the sealing member 201 according to an embodiment of the present invention has a structure in which a deformable portion is formed between the mounting base 21 and the connecting portion 23 by the mounting base 21, the outer wall 22, and the connecting portion 23. That's fine. Since such a sealing member 201 is formed with the deformable portion, even if there are manufacturing variations in the door holes D2 when viewed from the side of the vehicle, the door hole cap 1 can fit these door holes D2. can be well adapted to.

Further, in the sealing member according to an embodiment of the present invention, as shown by reference numeral 402 in FIG.
